Title: Cutting brittle materials
Inventor: YOUNG MICHAEL J R
IPC: B28D1/26
Filed: 1989-05-09
Granted: 1995-06-13
Abstract: A method of cutting a brittle workpiece comprises applying to the surface of the workpiece a pointed tool, applying high frequency vibrations in a longitudinal direction to the tool, and moving the tool along a line to be cut of the workpiece while applying substantially steady longitudinally directed pressure to the tool.  Stress is thereby applied to the workpiece as a combination of short impulses and steady direct stress and the breaking stress of the material would be attained coincident with the peak oscillatory stress.  Crack propagation would therefore proceed by a series of stepwise fractures induced by successive cyclic stress peaks, resulting ultimately in the separation of the workpiece into two pieces.  An apparatus for carrying out the method comprises a piezoceramic transducer to generate ultrasonic vibrations, a tip to be applied to the workpiece and having a hardness greater than that of the workpiece, and means to convey the ultrasonic vibrational energy to the tip.

The DPSK demodulator comprises a coarse frequency and lock detect module for identifying and estimating the frequency of the input signal, a numerically controlled oscillator (NCO) for generating in-phase and quadrature signals from the input signal, one pair each of delayed and non-delayed integrate and dump (I&D) modules, a symbol timing module for achieving symbol synchronization by determining the dump time of the I&D modules, a dot product detector for receiving the output of the non-delayed I&D modules and providing a detected data output, and an AFC loop comprising a cross product detector and an AFC loop filter that provides feedback to the NCO and lock detect module.  The DPSK demodulator achieves symbol synchronization independent of carrier phase or frequency and at low signal-to-noise ratios.  Overall, the modem achieves the theoretical bit error rate capability of DPSK on a narrow band, white Gaussian noise channel with minimal implementation loss.

IPC: G01F23/00
Filed: 1989-09-29

Abstract: This invention relates to a novel means for detecting a low level of liquid in a reservoir.  One application for the in-vention is to provide a way to indicate when the level of wind-shield washer fluid for a vehicle is at a low level.  According to one of its broad aspects, the windshield washer fluid noticeably changes colour on the windshield, when it is running low in the reservoir; for example, changing from very light blue to an intense red.  There are known electrical and mechanical means for indicating the level of a fluid in a reservoir.  However, these indicators of fluid level rely on special equipment such as floats and electrical contacts.  An advantage of the present invention, is that it can be used with existing windshield washer reservoirs without the need for additional equipment and/or gauges in the interior of the vehicle.  According to one aspect of this inven-tion, the windshield washer reservoir contains a first liquid which usually would be ordinary windshield washer fluid, normally of a light blue or light green colour and normally comprising a mixture of water, methyl alcohol and a dye.  Added to this first liquid in the reservoir is a second liquid having a specific gravity different from and floating on top of the first liquid such that when the first liquid is exhausted, the windshield washer delivery system will then pump, on to the windshield, the second liquid. This provides an advance warning the windshield fluid is running low; however the second liquid will continue to be available to clean the windshield for as long as previously planned.  The second liquid has a colour that is noticeably dif-ferent from that of the first liquid so that it is apparent that the first liquid has been consumed.  Hexyl alcohol is one example of a second liquid that is relatively immiscible with, and works well with ordinary windshield washer fluid as a first liquid.  The hexyl alcohol based second liquid can be coloured bright red, for example, with a dye that is relatively insoluble in the ordinary windshield washer fluid.

Abstract: An elevator control apparatus suppresses the jerk at the start-up of speed controlled elevator installations in both directions of travel, not only the friction jerk at the transition from the static friction to the sliding friction, but also the imbalance jerk at unbalanced car loads. A set point signal multiplier is connected to the output side of a set point memory in the hoist motor drive control and the set point multiplying factor can be controlled by way of an on/off circuit. The multiplier is switched, prior to the start of the movement, by the on/off circuit to a value greater than one, and is switched back to one at start of movement in the direction of travel. The motor driving force is controlled to a value which, when summed with the imbalance force, is equal to the sliding friction force at start-up. This suppression of jerks is eminently suitable for the refitting of controlled elevator drives and increases, due to the earlier start of movement, their elevating capacity.

Abstract: There is disclosed a linear block copolymer comprising at least one triblock I-B-I, wherein I is a block of at least one polymerized conjugated diene of at least five (5) carbon atoms, such as isoprene, and B is a block of a polymer of at least one conjugated diene, different from that used to polymerize the block I, of at least four (4) carbon atoms, such as 1,3-butadiene. The B block is selectively hydrogenated, while each of the I blocks is hydrogenated and therefore retains a sufficient amount of its original unsaturation to vulcanize the copolymer. There is also disclosed an alternative linear block copolymer containing at least one triblock of the first polymer block made from a minor proportion of at least one aryl-substituted olefin, such as styrene, and a major proportion of at least one conjugated diene used to polymerize the block I, the second middle polymer block of at least one diene used to polymerize the block B, and the third polymer block which is the same as the first polymer block. In this alternative copolymer, the middle block is also selectively hydrogenated, thereby leaving the terminal polymer blocks with a sufficient amount of their original unsaturation to vulcanize the copolymer. The polymers can be crosslinked or functionalized through the terminal blocks containing the vinyl unsaturation. There are also disclosed random linear and star-branched block and random copolymers made from the same monomers as the linear block copolymers. Also disclosed are methods of producing the polymers and selectively hydrogenating the aforementioned polymerized dienes.
